Umbilical arterial (UA) Doppler assessment is used in surveillance of fetal well-being in the third trimester of pregnancy. Abnormal umbilical artery Doppler is a marker of uteroplacental insufficiency and consequent intrauterine growth restriction (IUGR) or suspected pre-eclampsia.
A fetal Doppler is a handheld ultrasound device that looks like a small radio with a transducer attached. Doctors use it to listen to a yet-to-be-born baby's heartbeat. For most women, their baby's heartbeat should be detectable via Doppler by 12 weeks of pregnancy -- the end of the first trimester. However, there's a lot of individual variation in when the heart will become detectable.
